Abstract
The embodiment relates to a charging control device for an electric vehicle. An electric vehicle charging control device according to an embodiment includes: a charge sequence port to which a charging sequence signal is input from a connector of a charging cable; a first power supply for supplying a first driving voltage; a first controller which is driven on the basis of the first driving voltage, repeats a wake-up state and a sleep state periodically, and generates a wake-up signal when the charging sequence signal is input to the charge sequence port in a wake-up state; a second controller for maintaining a sleep state and operating in a wake-up state when the wake-up signal is generated during the maintaining of the sleep state, and for controlling a charging operation of the electric vehicle in the wake-up state; and a second power supply, disposed between the first controller and the second controller, for providing a second driving voltage to the second controller when the wake-up signal is generated, wherein the charging sequence signal is selectively received in the wake-up state of the first controller.
